Resumen
Aim of study: Septoria tritici blotch (STB), caused by the fungus Zymoseptoria tritici, is one of the most important wheat diseases worldwide, affecting both bread and durum wheat. The lack of knowledge about the interaction of durum wheat with Z. tritici, together with limited resources of resistant durum wheat material, have both led to a rising threat for durum wheat cultivation, particularly in the Mediterranean Basin. In Spain, STB has increased its incidence in the last few years, leading to higher costs of fungicide applications to control the disease. Therefore, identification of new s

Resumen
Pigments are essential to the life of all living organisms. Animals and plants have been the subjects of basic and applied research with the aim of determining the basis of the accumulation and physiological roles of pigments. In crop species, the edible organs show large variations in colour. In durum wheat grain, which is a staple food for humans, the colour is mainly due to two natural classes of pigment: carotenoids and anthocyanins. The carotenoids provide the yellow pigmentation of the durum wheat endosperm, and consequently of the semolina, which has important implications for the marke

Resumen
Fusarium head blight (FHB) is a major fungal disease affecting wheat production worldwide. Since the early 1990s, FHB, caused primarily by Fusarium graminearum, has become one of the most significant diseases faced by wheat producers in Canada and the United States. The increasing FHB problem is likely due to the increased adoption of conservation tillage practices, expansion of maize production, use of susceptible wheat varieties in rotation, and climate variability.

Resumen
Carotenoids are essential in the human diet for their important functions in health. Besides, they are responsible for the yellow pigments desirable for industrial quality in durum wheat. The remarkable carotenoid content of durum wheat endosperm is mostly due to lutein. However, lutein esters have not been previously detected in durum wheat as in other cereals such as common wheat, tritordeum or Hordeum chilense. Esterification increases carotenoid stability and allows greater retention and accumulation through the food chain. Therefore, carotenoid esterification is revealed as a new key targ

Abstract Development of efficient DNA markers plays an important role in modern breeding projects of many crops, including cultivated hexaploid bread wheat (BW) and tetraploid durum wheat (DW). Findings of genome-wide association studies on major polyploid crops, such as BW, may also help in molecular breeding studies in relative cultivated species with a similar genetic background, including DW. Therefore, the validation of identified quantitative trait loci or marker-trait associations is an important preliminary step in marker-assisted selection (MAS) oriented projects.

Durum wheat is an important food crop in the world and an endemic species of sub-Saharan Africa (SSA). In the highlands of Ethiopia and the oases of the Sahara this crop has been cultivated for thousands of years. Today, smallholder farmers still grow it on marginal lands to assure production for their own consumption. However, durum wheat is no longer just a staple crop for food security but has become a major cash crop. In fact, the pasta, burghul and couscous industry currently purchase durum grain at prices 10 to 20% higher than that of bread wheat. Africa as a whole imports over €4 billio

Resumen
Grain protein concentration is important in the determination of the value of durum wheat (Triticum turgidum L. var. durum) for pasta manufacture. This study was undertaken to investigate the heritability and inheritance of protein concentration in seven genetically diverse durum populations, and to determine if the precision of this information could be improved by adjustment for micro-environmental trends. Grain protein and grain yield were measured at multiple locations and years. The Papadakis method was used to adjust for environmental trends in these replicated trials, and the moving mea

SUMMARYRainfall and temperature are unpredictable in Mediterranean environments, which results in inconsistent environmental conditions for crop growth and a critical source of uncertainty for farmers and growers. The objectives of the present study were to: (i) quantify and compare the plasticity of durum breeding lines, a modern cultivar and landraces on the basis of yield and agronomic traits and (ii) study associations between plasticity of yield and plasticity of agronomic and phenological traits. Plasticity was quantified using linear models for 11 durum breeding lines, one modern cultiv

AbstractWe calculate the welfare effects of the Washington State University (WSU) wheat breeding programs for producers and consumers in Washington, Oregon, Idaho, and the United States, and for importers of U.S. wheat. We develop a partial equilibrium multiregion, multiproduct, multivariety trade model for wheat that provides consumer, producer, and total surplus for each wheat class and region. Our results provide evidence suggesting that WSU wheat breeding programs have increased welfare for the state of Washington, the United States, and importers of U.S. wheat.

Resumen
Red seed-coat can be distinguished from white seed-coat of unground wheat (Triticum spp.) by measurement of the first-derivative of the reflectance spectra at approximately 516 nm. Values around 450 nm distinguish durum (T. turgidum L. var. durum) from common (T. aestivum) white types. Classification accuracy is sufficient for screening purposes to reduce the number of samples requiring further examination. For breeding programs currently using combination near-infrared/visible (NIR/VIS) instruments, the additional time and costs to process the seed-coat information are minimal. Key words: Red

The results of immunological assessment of varieties of durum and soft winter wheat bred by the Agrarian Scientific Center Donskoy for resistance to leaf rust are presented. The experiment was carried out in Krasnodar Territory in 2016–2019. Screening of 86 selection samples (63 varieties of durum winter wheat and 23 samples of soft winter wheat) was carried out in an artificial infectious environment. To infect plants, a population collected during route surveys of production and selection crops of winter wheat was used. The varieties were assessed according to two criteria: the type of react

Resumen
Triticum timopheevii (Zhuk.) Zhuk. is noted for its resistance to diseases including leaf and stem rust of wheat. Only one gene (Lr18) for leaf rust resistance has been transferred from T. timopheevii to bread wheat. The objectives of this work were to study the inheritance of leaf rust resistance in five accessions of T. timopheevii and to transfer genes for resistance into durum and bread wheats. A diallel set of crosses was made among five T. timopheevii accessions that gave a fleck infection type with an isolate of leaf rust race CBB. None of the F2 populations of the 10 crosses segregated

AbstractThe valorization of genetic diversities of major crops like wheat may help substantially to feed the world Population. Durum wheat genotypes consisting of 265 farmers’ varieties (FVs), which have been cultivated for many centuries in Ethiopia, as well as 24 improved varieties (IMVs) have been recently evaluated in northern Ethiopia. The evaluation has been carried out at two different locations for 2 consecutive years to verify the inherited diversity in FVs for important phenological and agronomic traits; with the intention to provide refined information to breeders and genebank manag

Resumen
Durum wheat (AB genomes) is more salt-sensitive than bread wheat (ABD genomes), a feature that restricts its expansion into areas with sodic or saline soils. Salt tolerance in bread wheat is linked with a locus on the D genome that results in low Na+ uptake and enhanced K+/Na+ discrimination. In order to introduce salt tolerance into current durum wheats from sources other than the D genome, a search for genetic variation in salt tolerance was made across a wide range of tetraploids representing 5 Triticum turgidum sub-species (durum, carthlicum, turgidum, turanicum, polonicum).

Resumen
The selection of genotypes under high soil fertility may alter the effectiveness of mycorrhizal symbioses naturally forming between crop plants and the mycorrhizal fungi residing in cultivated fields. We tested the hypothesis that the mycorrhizal symbiosis of 5 landraces functions better than the mycorrhizal symbiosis of 27 cultivars of durum wheat that were bred after the development of the fertilizer industry. We examined the development of mycorrhiza and the response of these genotypes to mycorrhiza formation after 4 weeks of growth under high and low soil fertility levels in the greenhouse
